Application filed July 2:,

This invention relates to a concrete. con-.

veying and distributing cart, and especially to a cart ofthis characterwhich is particularly adapted for delivering, distributing and'spreadingwet concrete in a series of successively arranged molds.

The object of the present invention is to generally improve and simplifythe construction and operation of carts of the char-.

. acter described; to provide a cart which is It Is also provided withsupporting legs 14,

adapted to straddle a series of molds placed end for end in lineformation and to be moved longitudinally thereof; a cart from which theconcrete begradually' discharged as it is being moved with relation tothe molds, so thatthe successive molds may be filled; and further, toprovide adjustable means whereby the flow of the discharging concretemay be regulated and the final height of the termined.

One form which my invention may assume is exemplified in thefollowingdescription and illustrated in the accompanying" drawings, in which Fig.1 is a perspective View of the con crete conveying and distributingcart;

Fig. 2 is an end view of the same, showing it in position with relationto a mold.

Fig. 3 is a cross-section of the. vertical end of the concrete cart,showing the position of the gate and the guide flanges supporting thesame.

Referring to the drawings in detail, and

particularly to Figs. 1 and 2, A indicates in general a V-ahaped hoppersupported by; wheels B. The hopper consists-of avertical 'end section 2,an inclined end section 3, and

a pair of vertical side sections 4. The lower portion of the verticalend section 2 is cut away to form a discharge opening 5, and a gate 6 isvertically movable with relation thereto to close the opening or topartially or fully uncover the same when concrete is being dischaged.The'gate 6 engages the forward face of the end section 2 and is held insliding contact therewith, the gate being tion to the end section 2. Apair of crank arms 9 is secured to the shaft and these crank arms areconnected through links 10 with the gate. Shaft 8 is also provided witha crank concrete in the molds de- 192s. Seria1No.'727,667. I

handle 11 i which is manually controlled. This crank handle when pulledin one directionturns shafts 8' so to raise thecrank arms 9, the linkslO-and the gate 6. llfovement of the crank handle 11 in the oppositedirection reverses the movement. The discharge opening may thus be,closed or partially, opened-as desired by the operator.

The cart is otherwise provided with a. push bar 12 secured to handleextensions 13.

spreading device consists of .a plate 15 disposed in front of the gate6- and on an-angle with relation thereto.- The plate 15 is secured tothe end sections 4 of the hopper by means of side plates 16. These side,plates are 'inturn provided with supporting legs or shoes 17 which areadjustable with relation to the plates 16-; that is, the upper ends ofthe shoes are slotted as shown at.18 and bolts .19 extending throughtheslots and secured in the plates 16 permit vertical adjustment of thelegs. H y

The cart is particularly adapted for use inconnection with a new methodof molding concrete blocks andglike devices,. such as illustrated anddescribed. in my issued patent v entitled Method and apparatus formanufacturing hollow concrete building blocks.- issued July 28 1925,Patent No. 1,547,530. Briefly the method consists in placing a series ofmolds endfor-end in line formation on'a suitable support, such asindicated at 20. Runways 21 are formed on each side of the support andV-shaped grooves or tracks are formed in the runways for the receptionand guidance ofthe wheels B.

The concrete wet-mix is formed in a suitable concrete mixer and the likeand is dumped into the hopper of the cart. The cart is then advancedover the runways illustrated and is guided by the V-shaped grooves ortracks.

The cart will thus straddle the molds indicated at 24 and each mold willbe. successively filled by opening the gate 6 as the cart is advanced.The amount of concrete discharged is regulated by'the position of thegate and the levelling or spread ing plate 15; that is,.the concretemight have a tendency to'bunch in places, but it is even 1y s read outand a uniform height in the mol s is obtained by the plate 15 as itserves a levelling and spreading device; the

I position of the plate 15 with relation to claims.

.. I claim and desire to secure by Letters operated lever movement tothe gate, a combination spreadthe molds being determined by the shoes17, which are held in frictional contact withthe runways as the cart isbeing advanced. If it is desired to spread the concrete, so that it willproject one-fourth of an inch above the molds, it is only necessary toadjust the legs 17 so that when the card straddles the molds and isadvanced with relation to the same, a clearance of onefourth of an inchwill be obtained when the legs 17 contact with the runways. A greater orless clearance may, of course, be obtained by changing the adjustment.

It has heretofore been common practice accomplished in one operationwhen the cart here shown is employed, and a saving in both time andlabor is thus obtained.

While certain features of the present invention are more or lessspecifically illustrated, I wish it understood that various changes inform and proportion may be resorted to within the scope of the appendedI similarly wish it understood that the materials and finish of theseveral parts employed may be such as the experience and judgment of themanufacturer maydictate or various uses may demand.

Having thus described my invention, what Patent is- 1. A cart of thecharacter described, comprising a concrete receiving hopper having adischarge opening formed in its lower end and extending substantiallyfrom side to side of the hopper, a sliding gate vertically movable withrelation to the opening for closing said opening and for regulating theflow of concrete therethrough, a manually for transmitting sliding ingand leveling plate carried by the hopper, and'wheels supporting andpermitting longitudinal movement-of the hopper.

2. A cart of the character described, comprising a concrete receivinghopper having a discharge opening formed in its lower end,

a gate movable with relation thereto, manually-actuated means foropening and closing the gate and for regulating the flow of concretethrough the discharge opening, andin said late bein dis osed on avvertical.

inclination with its upper edge closest to the hopper, an end plate oneach endof the spreader plate and. a connection between each end plateand the hopper.

' 4. In a device of the character described, a hopper which. is V-shapedin cross section, a substantially vertically disposed end plate in thehopper and having an elongated dis charge opening formed in its lowerend, a

gate vertically slidable on the end plate for opening or closing thedischarge opening and for regulating the discharge of concrete, and aninclined spreading and levelling plate carried by the hopper andvdisposed rearwardly of the discharge opening.

5. A wheel supported cart of the. character WOLCOTT P. STANTON.
